IGN : Shielded Details: Everytime I used the skill "Threaten" my computer (laptop) just froze, it's not a normal disconnect, bugs. I can't seem to do anything in maplestory neither my Desktop. My guess is this bugs somehow create a Dump File (I don't really know computer tech) ? Sorry for I can't provide any screen shot, but as I've said before, I can't do anything after the bug happen on my laptop except restart.
Can you try re install mapleroyals with your firewall and antivirus disabled, I have never heard of this problem before.
